Finally I have resolved an issue I posted on a thread a couple of weeks ago about an unexpected file corruption than didn't let me boot win xp pro. I solved it using ontrack system suite 4.0 registry fix. Honesltly I never thought it will fix it, i installed it to get a decent firewall and AV software and as an option to Norton SS which apparently has many issues with XP. After testing XP by rebooting several times and installing games and programs and then unistalling them , I decided that the system was finnally stable and installed office xp and publisher 2002. I rebooted and now can't log into windows, safe mode or last known configuration don't work. Windows displays a mesage that says that they apologise for the inconvenience, but a recently installed application has caused the system to crash and cannot boot. Now aren't office and publisher Microsoft applications that are supposed to work smoothly under Windows XP??? All programs total $600+...!!
